OVERVIEW

Mastering Light Curing in Direct Resin Restorations is organized by University of Maryland School of Dentistry (UMSOD) and will be held on Sep 03, 2025.

Description:
This course provides a detailed and practical overview of the principles behind light curing in resin-based restorative dentistry. Through an evidence-based approach, participants will explore the science of photopolymerization and the variables that critically influence its success in clinical applications.

We will begin by understanding the role of light curing units (LCUs) and the chemical events that occur during the polymerization of resin composites. The course will then focus on key factors that directly affect polymerization, such as the compatibility between the light wavelength and photoinitiators, the power output of curing devices, and how exposure time, distance, and angulation impact the quality of curing.

Participants will also learn about the clinical implications of these factors, including how they affect restoration longevity, marginal integrity, and the risk of postoperative sensitivity or secondary caries. This course is designed to help clinicians optimize their use of LCUs and make informed decisions that enhance clinical outcomes.

Learning Objectives:
At the conclusion of this course the participants should be able to:

Define the role of light curing units and understand their operating principles.
Describe the key stages and mechanisms of the resin polymerization process.
Identify and evaluate the factors that influence the success of light curing:
- Photoactivator wavelength
- Type and concentration of photoinitiators in composites
- Curing light power and intensity
- Relationship between light intensity and light guide tip size
- Exposure time and energy density
- Curing angle and distance from the restoration
Apply optimized light curing techniques to improve restoration outcomes and longevity.
Troubleshoot common clinical issues related to inadequate polymerization.
